direct route to Mauritius. The NE course will lead first into an area of variable winds and calms. The SE trade winds can sometimes be found as far south as 30 °S and, once found, they should ensure a fast passage for the rest of the voyage. The best month for this passage is May when the cyclone season has come to an end in the South Indian Ocean and the winter gales of higher latitudes are only about to begin.

Mauritius will be approached from the south by a route which will pass east of Réunion Island. Landfall will be made at WP IS623, off Cape Brabant, the SW extremity of Mauritius. From there the course can be altered for WP IS624, in the approaches to Port Louis.

reported to be sometimes out of action. The course can then be altered for WP IS613, north of Mahe's North Point, in the approaches to Port Victoria. This is entered through the main shipping channel.

Boats leaving from a Tanzanian port, such as Dar es Salaam, follow a similar route. From WP IS614, in the approaches to Dar es Salaam, a direct course can be set for WP IS612. The rest of the route is similar to the one described above.

Few boats attempt to sail a rhumb line between these two points becaiuse of the strong south-flow-ing Agulhas current and the high probability of encountering contrary winds. The recommended tactic is to make easting with the help of the prevailing westerly winds of higher latitudes. On leaving Durban, from WP IS621 a SE route is taken so that, depending on weather conditions, easting is made between latitudes 30 °S and 35 °S. However, one should be prepared to go even further south in search of westerly winds, possibly as far as 40 "S. Strong westerlies should be encountered in those latitudes and also frequent squalls. Having sailed at least 800 miles in a SE direction, a point will be reached where the course can be altered for a more
